RECOM Switching Regulator, Through-Hole Mounting, DC-DC Conversion - R-78E-0.5 Series - R-78E12-0.5

Need a stable 12V DC supply for your equipment? This switching regulator from RECOM takes an input voltage anywhere between 15V and 28V DC and outputs a steady 12V DC. Line regulation of ±0.5% and load regulation of ±1% ensure a consistent supply, even if there are fluctuations in supply and demand. High efficiency of 95% reduces heat dissipation, meaning you won't need a separate heatsink. The Compact SIP3 package saves space on your board.

Features & Benefits

• Operating temperature range of -40°C to +85°C makes it suitable for harsh environments

• Ripple and noise of 70 mV Pk-Pk reduce risk of damage due to overheating

• MTBF of 2,182,000h at +85°C for a long service life

• Through-hole mounting creates a strong connection with your PCB

Applications

• Military hardware

• Steel mills

• Lifts

What's load regulation?

Load regulation is the measure of a power supply's Ability to output a constant voltage when the output current fluctuates. The smaller the percentage, the more stable the supply.

What's line regulation?

Line regulation is similar to load regulation in that it's a measure of a power supply's Ability to maintain a constant voltage despite fluctuations in current. Load regulation refers to the output, whereas line regulation refers to the input.
